BY MARK SCHOLZ, MDAs a medical oncologist specializing in prostate cancer, the question I am asked by patients almost daily is, “What new treatments are coming for prostate cancer?” Fortunately, there are so many new developments I am able to give answers that vary depending on the stage (or Shade, to use PCRI terminology) of the person asking, since they are usually interested in developments relevant to their specific situation.

However, if I am asked a slightly different question—“What type of new technology has the greatest potential for saving lives?”—my answer will always be the same for every patient: Immune therapy. Let me explain why.

Before the intricate complexity of cancer biology was recognized—through the amazing work of thousands of biochemical researchers—people were hoping a single magic bullet could be discovered that would cure cancer. That hope has been dashed because we now know there are innumerable variations of what we call “cancer.” Waiting for the discovery of a single type of treatment universally effective against all types of cancer is quite naive.

However, there is one intrinsic capacity in our bodies that successfully parries millions of different attacks on our health: the immune system. Therefore, if a cure for the myriad of different cancer types exists, it will probably result from successfully harnessing this incredible system.

One fallacy believed by almost all patients is that their cancer is the result of a weak immune system. Their logic is that their immune system somehow has to be weak considering that the cancer has not been kept under control. Actually, if we are going to speak figuratively about the immune system, the problem is better characterized as an issue of blindness rather than one of weakness.

Early success in using the immune system to overcome scourges such as polio caused cancer researchers to study vaccine type methods for stimulating the immune system to attack cancer,unfortunately with only modest results. The problem is that cancercells have mechanisms that enable them to hide from the immune system.

The fairly recent discovery of this capacity for cancer to cloak itself represents both good news and bad. Without a specific target to attack, simply making the immune system “stronger” is useless. The good news is that a properly directed immune system can and will eradicate cancer.

Prostate cancer is one of the few types of cancer for which an immune therapy has been approved by the FDA. Dendreon, the company that manufactures the immune treatment called Provenge, has developed technology to remove and purify dendritic cells, the specific immune cells in the body that can detect cancer. Once in the lab the dendritic cells are “force fed” with a cancer-specific protein. After being reinjected into the body, these invigorated immune cells recruit additional cells of the immune system that specifically focus their attack on the cancer cells displaying that cancer-specific protein.

Double-blind, placebo-controlled trials show Provenge slows cancer progression and prolongs survival just as well or even better than other standard treatments such as chemotherapy or second-line hormonal therapy. None of these treatments consistently eradicate cancer. They do, however, act to keep it in check for a period of time.

To obtain better results the next logical step is combining one form of immune therapy—Provenge—with some other immune therapy with the hope of further enhancing the anti-cancer effect. My next blog will discuss a new study we are conducting in my clinical practice at Prostate Oncology Specialists using Provenge in combination with “Yervoy,” a monoclonal antibody from Bristol-Myers Squib. Generically Known as ipilimumab, Yervoy is an FDA-approved immune treatment shown to prolong life in people with metastatic melanoma. Yervoy functions by “taking the brakes” off the immune system.

BY RALPH BLUMIn my last blog, I
said that after all this time living with prostate cancer the uncertainty was
beginning to wear on my nerves. At this point, and having thoroughly
researched all my options, the idea of having my prostate fried by electrons
doesn’t seem quite so alarming, and as four-letter words go, “cure” has a sweet
ring to it.

I’m talking about IMRT, which is short for Intensity Modulated Radiation
Therapy. IMRT is a precisely targeted procedure that allows the physician to
control the intensity of the radiation beam within a given field. This means
that a much higher dose may be given to a tumor within the prostate without an
increase in radiation to the surrounding tissue or organs. And if the cancer
has spread through the wall of the prostate gland into the seminal vesicles (as
in my case) the target field and dosage can be adjusted as necessary.

The big advantage of IMRT over regular external beam radiation is that the beam
can be shaped to the exactdimensions
of the area to be radiated. And instead of a solid beam of uniform intensity,
it utilizes a variety of small independent beams known as “multileaf
collimators” that can be turned on or blocked during treatment, varying the
radiation beam intensity across the targeted field.

Because of the complexity of the treatment plan, radiation oncologists employ
special high-speed computers, treatment-planning software, diagnostic imaging,
and positioning devices molded to fit the precise contours of the individual
patient. Typically a patient will be required to have several scans, and a team
consisting of a radiation oncologist, a medical physicist, a dosimetrist (who
sets the radiation dosage), a technician (who does the set-up session), a
therapist and a radiation oncology nurse will oversee the treatment.

As with conventional radiation therapy, multiple treatments are required, but
with IMRT, the eight-to-nine weeks of treatments (lasting about twenty minutes
each) significantly lower the risk of adverse side effects, and the chance of a
cure is substantially higher. When I first saw the twelve-foot tall linear
accelerator in the treatment room I have to admit I found the idea of having a
mountain of energy shot at my pelvis from this giant ray gun--the muzzle of
which would be situated barely two inches from my pecker--extremely daunting.
And the matter of “rectal burn” cannot be ignored. However I have been
assured that with IMRT rectal irritation is generally temporary, and can be
relieved with medication.

So it’s decision time again. I still wish I could safely stay on Active
Surveillance, but with IMRT the odds are favorable for a cure, Dr. Bahn has
advised me to go for it, as has Dr. Scholz. Even I, the ultimate “Refusenik,”
suspect it is time to act.

BY RALPH BLUMIn my Blog “Nervous Moments” I wrote about the sinking feeling in my gut—half panic, half “Oh s--t!”—when I learned that my PSA had spiked to 26. Since then I have done a course of Cipro, in order to determine whether the hike was a result of an infection (Jeanne and I had both had the flu). And I made an appointment with Dr. Duke Bahn for a color Doppler MRI.

If I had a significant bout of the flu, it wasn’t severe enough to effect my PSA which, on re-checking after the course of Cipro, was undiminished. The result of Dr. Bahn’s test showed a small but discernible progression of the cancer. Not what I wanted to hear, and as a result of his findings (pointing out on the images the enlarged dark cancer patches) I began to entertain serious thoughts of finally getting treated. But before determining the type of treatment I had to determine that the cancer hadn’t spread to my lymph system, or to my bones.

So it was back into the clickety-clack, thumpa-thumpa-thump of the MRI machine, with Vivaldi’s “The Four Seasons” soothing my ears. I admit, I rather enjoy the contrast: flutes and strings and kettle-drums. Directly following the MRI, I went next door for a bone scan.

The first results were provided by the same dayfollowed the next afternoon by the results of the bone scan (“No evidence for any spread of cancer.”)The news was great. Both were clear. Big sigh of relief. Thank you, God! So now the question is: to treat or not to treat? I started this journey back in 1990 when I was 58 years old, and apart from 15 months on hormone blockade (a single drug protocol with Lupron when my PSA last spiked in 2003), I have monitored my cancer with Active Surveillance. And now, at eighty I still have options.

I’m still in the process of decision-making. But I’m getting tired of the uncertainty, and I’m leaning toward placing myself in Dr. Lisa Chaiken’s competent hands. Dr. Chaiken is the chief radiation oncologist at the Santa Monica Treatment Center, a state-of-the-art facility for Intensity Modulated Radiation Therapy (aka IMRT) at St. John’s Hospital in Santa Monica.

So, finding myself at the decision point once again, in my next Blog, I will take a closer look at IMRT. The odds are that it will become my treatment of choice.
